HSS Appoints Valarie McPherson as Vice President, Ambulatory Operations and Clinical Services

Hospital for Special Surgery (HSS), the world's leading academic medical center focused on musculoskeletal health, today announced the appointment of Valarie McPherson, DNP, MBA, NEA-BC, as Vice President, Ambulatory Operations and Clinical Services.

This newly created role reflects HSS's continued focus on expanding and integrating its ambulatory footprint to support high-quality care across sites.

McPherson will be responsible for leading system-wide ambulatory operations, with oversight of ambulatory surgery centers, outpatient clinics, and select ancillary services. In this role, she will drive operational performance, standardization, and coordination across sites to advance HSS's growth and care delivery priorities.

"Val's appointment strengthens our ability to deliver a more coordinated, high-performing ambulatory model at scale," said Mary Cassai, executive vice president and chief operating officer at HSS. "Her experience leading complex clinical operations and driving performance across sites will be important as we expand access to more patients across the New York Tri-State region and enhance the patient experience."

McPherson joins HSS from Hackensack Meridian Mountainside Medical Center, where she served as Chief Operating Officer and Chief Nursing Officer. She brings more than 25 years of experience leading clinical and operational functions across complex health systems.

"Val is a highly accomplished healthcare executive with deep experience in leading complex clinical operations," said Douglas E. Padgett, MD. "She will play a key role in strengthening our ambulatory platform and supporting continued growth across the system."

"HSS has set the standard for musculoskeletal care through a clear focus on quality and outcomes," said McPherson. "I'm looking forward to advancing the operational capabilities that support that care-expanding access, improving efficiency, and ensuring a seamless experience for patients."

McPherson joins HSS on April 27, reporting directly to Mary Cassai.
